While certainly not equal to the level of measurements Amir would perform, something better than nothing …


I have extensive experience both with older versions of SL’s designs (including owning the original Orion years ago) and this latest incarnation and they are outstanding loudspeakers. Not many speakers I have heard portray as holographic a soundstage as these do. The only reason they are not on my endgame shortlist is the output falls a bit short for larger rooms.

At first I thought this looked pretty rough:

But they've made the X axis cover only 20 dB, which is exaggerating the peaks and troughs.

Setting the X and Y limits similarly on my own in-room measurements makes them equally lumpy:

It looks far better like this: :)

Regardless, I've been aware of the Linkwitz speaker designs for some time and I would very much like to hear some. However, open baffle designs are unlikely to work well in my room. :confused:

Nice catch on the plot axis!

And yup, these (as with all dipoles) definitely need some room to breath
